Injury Severity Score
Medical score to assess trauma severity / From Wikipedia, the free encyclopedia
The Injury Severity Score (ISS) is an established medical score to assess trauma severity.[1][2] It correlates with mortality, morbidity and hospitalization time after trauma. It is used to define the term major trauma. A major trauma (or polytrauma) is defined as the Injury Severity Score being greater than 15.[2] The AIS Committee of the Association for the Advancement of Automotive Medicine (AAAM) designed and improves upon the scale.
